Deficiency in T follicular regulatory cells promotes autoimmunity. [PDF]

J Exp Med, 2018
T follicular regulatory (Tfr) cells are a new subset of regulatory T (T reg) cells localized in the germinal center to limit the humoral response. Until now, the physiological function of Tfr cells has been largely unknown. In this study, we developed a Bcl6fl/flFoxp3Cre mouse to analyze the function of Tfr cells in immune and autoimmune responses ...

Mechanisms of t follicular regulatory cell differentiation

Respostas imunológicas humorais protetoras coordenadas pelas células B, quer em resposta a infeções ou à vacinação, requerem a participação de células T. Entre estas, as células T foliculares auxiliares (Tfh) emergiram como elementos-chave, fornecendo ajuda às células B e facilitando a produção de anticorpos de alta afinidade.

The multifaceted functions of follicular regulatory T cells

Current Opinion in Immunology, 2020
The immune system is capable of generating robust antibody responses to foreign antigens during infection and vaccination, while simultaneously limiting antibodies to self-antigens. T follicular regulatory (Tfr) cells are a subset of follicular T cell with specialized roles in regulating humoral immunity.

T follicular regulatory cells in the regulation of B cell responses. [PDF]

Trends Immunol, 2015
High affinity antibodies result from interactions between B cells and T follicular helper (Tfh) cells in germinal centers (GCs). Recent studies have identified an effector subset of T regulatory cells termed T follicular regulatory (Tfr) cells that specifically controls GC responses by suppressing Tfh and B cells.

ICOS controls Foxp3+ regulatory T-cell expansion, maintenance, and IL-10 production during helminth infection [PDF]

, 2012
Foxp3+ regulatory T (Treg) cells are key immune regulators during helminth infections, and identifying the mechanisms governing their induction is of principal importance for the design of treatments for helminth infections, allergies and autoimmunity ...

The Phenotype of Circulating Follicular-Helper T Cells in Patients with Rheumatoid Arthritis Defines CD200 as a Potential Therapeutic Target [PDF]

, 2012
Rheumatoid arthritis (RA) is a systemic autoimmune disease primarily affecting synovial joints in which the development of autoantibodies represents a failure of normal tolerance mechanisms, suggesting a role for follicular helper T cells (TFH) in the ...

Harnessing Activin A Adjuvanticity to Promote Antibody Responses to BG505 HIV Envelope Trimers

Frontiers in Immunology, 2020
T follicular helper (TFH) cells are powerful regulators of affinity matured long-lived plasma cells. Eliciting protective, long-lasting antibody responses to achieve persistent immunity is the goal of most successful vaccines. Thus, there is potential in

Continually recruited naïve T cells contribute to the follicular helper and regulatory T cell pools in germinal centers

Nature Communications, 2023
Follicular helper T cells (TFH) mediate B cell selection and clonal expansion in germinal centers (GCs), and follicular regulatory T cells (TFR) prevent the emergence of self-reactive B cells and help to extinguish the reaction.

TFR Cells Express Functional CCR6 But It Is Dispensable for Their Development and Localization During Splenic Humoral Immune Responses

Frontiers in Immunology, 2022
Follicular T cells including T follicular helper (TFH) and T follicular regulatory (TFR) cells are essential in supporting and regulating the quality of antibody responses that develop in the germinal centre (GC).

Compromised function of regulatory T cells in rheumatoid arthritis and reversal by anti-TNF alpha therapy [PDF]

, 2004
Regulatory T cells have been clearly implicated in the control of disease in murine models of autoimmunity. The paucity of data regarding the role of these lymphocytes in human autoimmune disease has prompted us to examine their function in patients with
